The euro crumbled to a new 12-year low overnight

The euro is up 0.44% this morning, as of 9:07 GMT (5:07 ET), flirting with $1.06 — but overnight it sank to a fresh 12-year low, under $1.05. That's the first time it's been below that level since January 2003, 12 years and two months ago.

The weakest spot came just before 4 a.m. GMT (midnight ET). Here's how it looked:
